The grinded leaves of Piper sarmentosum were extracted by using two different solvent which were chloroform and ethanol. The method used in the extraction process was Soxhlet apparatus method. The extracts then were concentrated and evaporated by using rotary evaporator to produce crudes. The percentage yield obtained for ethanol extract was higher with 10.50 % compared to the chloroform extract with percentage yield of 8.92 %. Each of the crudes also was analyzed by TLC profile in order to determine the suitable combination of solvent system that can separate the compounds. In phytochemical screening analysis, the ethanol extract has indicated the presence of flavonoid, tannin, terpenoid, alkaloid and phenolic compounds, but not for saponins. Meanwhile, chloroform extract showed only the presence of saponin compounds but the rest were negative. Each of the crudes was also tested for their biological activities towards four different bacteria by using the disc diffusion method. The Gram-negative bacteria used which were Escherichia coli and Salmonella typhimurium while the Gram-positive bacteria used which were Bacillus subtilis and Staphylococcus aureus. Inhibition zone from the reaction of the extracts towards the bacteria was observed and measured. The antibacterial activities of the extracts were shown on S. typhimurium, B. subtilis and S. aureus, except for E. coli.
